For me... 4 weeks post treatment my weight had dropped to about 9olb... I would sleep, wake up, puke, feed, puke, sleep, wake up, puke..... I think you get it. I couldn't walk to the bathroom without ricocheting down the hall way. I was so weak, low blood pressuare, wasting away, oh my gosh! & completely uncoperative with my family and loved ones who were just trying to help. I don't think doctors explain just how bad it can get post treatment.
But on a good note, i'm great now! Working full time and setting up my own business. For me things didn't start to improve until 12 weeks post Tx.
I do hope things start to look up for your mum soon though.
